As of right now, the setFocusPoint and setExposurePoint methods in the camera plugin do not correctly rotate the supplied coordinates according to the UI orientation, causing them to only show correct behaviour in one orientation. For Android this is landscape left, on iOS portrait up. This can be reproduced by running the example app in any other orientation, as it can be seen the camera will focus somewhere other than where the preview widget was tapped. (Be sure to lock the autofocus first on Android)

• A fix for the Android side is already included in part 9 of the Android refactor that is currently going on (PR [camera] android-rework part 9: Final implementation of camera class plugins#4059)
• I am currently submitting a PR for the fix for iOS. A fix for iOS has now been submitted merged in [camera] Fix coordinate rotation for setting focus- and exposure points on iOS plugins#4158
